Jose Mourinho is preparing to invest in new full-backs on both sides in the summer as he will offload Daley Blind and Matteo Darmian, according to the Manchester Evening News. 

What's the story?

Mourinho is planning heavy investment in both a right-back and a left-back, with Juventus' Alex Sandro reportedly on top of the wishlist, ahead of Danny Rose and Kieran Tierney.

There are no names identified for the right-back slot but Mourinho is aware that Antonio Valencia is not getting any younger. Timothy Fosu-Mensah may be able to deputise next season, but one more experienced addition is wanted.

Blind and Darmian are all but out of the door and Luke Shaw may join them. If the England international does leave, it is thought that Mourinho could "do a Manchester City" and sign three full-backs in the summer.

Mourinho has to get it right

In letting Blind, Darmian and maybe Shaw leave, Mourinho is allowing millions of pounds worth of international talent - signed at great expense by Louis van Gaal - leave Old Trafford.

That signals the end of the latest attempt to resolve the full-back issues at the club, that have lingered since the respective departures of Gary Neville and Patrice Evra.

Valencia and Ashley Young, both converted wingers and remnants of the Sir Alex Ferguson era at Old Trafford, have established themselves as first-team fixtures.

However, both can be upgraded with heavy investment - just like City did last summer when they traded their aging options in for Kyle Walker, Danilo and Benjamin Mendy - and that is what Mourinho will be looking to do.

Nevertheless, it is important that he gets this whirl of the merry-go-round spot on. That's because, given the age of Valencia and Young, these new men will likely be United's options for the foreseeable future. Jose has to get this buys right.
